Flowers of Evil — N.L. Holmes

When two young women in ancient Egypt open a medical dispensary, they don't expect their first patient to be a dying florist of Amen whose last words are totally mysterious. It's Neferet and Bener-ib's nature to want to appease the ba of the murder victim by finding his killer, and their teenaged apprentice is a born detective. But between the skepticism of their own families and the malice of a rival healer, they find out the simple desire to do the right thing gets them into more trouble than they could have imagined!
